HD11F knife switch
1.Description:
HD and HS Series open knife and knife transfer switch (hereinafter refered to switch) are suitable in the assembled distrbuting equipment of AC 50Hz rated voltage up to 380v,or DC up to 220v and rated current up to 3000A,used to infrequently make and break the AC or DC circuit in hand or acted as isolating switches.
This production is in comforming with standard GB14048.3 IEC60947-3.
2, Character
==>Central handgrip style are mainly used in power station and acted as isolating switches,they are not intended for break the circuit with current.
==>Side handgrip style switches are mainly used in power box.
==>Central front lever operating mechanism style switches are mainly used in the front side operated,rear maintained switchgear cubicle,the operating mechanism can be fixed in the front of the cubicle.
==>Side front lever operating mechanism style switchs are mainly used in front side operated,front maintained switchgear cubicel,the operating mechanism can be fixed on both side of the cubicle.
==>The knife switch equipped with arc chute can cut off the current load,Knief switch of other series are acted as isolating switches only.
